What's the Difference Between a Percentage Change and a Percentage Rate?
Many people use the terms "percentage change" and "percentage rate" interchangeably, but there's a key difference between them. A percentage change is the change in a value expressed as a percentage, while a percentage rate is a fixed rate of return or increase, often expressed as a decimal. To illustrate the distinction, consider an investment that returns 5% each year. The percentage change would be 5% in any given year, while the percentage rate would be 0.05 as a decimal.

To calculate the percentage change, you'll need to take the negative change in value, divide it by the original value, and then multiply the result by 100 to convert it into a percentage.
